Application filed March 30, 1911. Serial No. 617,907.

To all whom t may concern Be it known that I, WENDELL RICE, a citizen ofthe UnitedStates, residing at Caldwell, in the county of Canyon andState of Idaho, have invented certain 'new and useful Improvements inCalculators; and I do hereby declare the following to be a full, clear,and exact description of the such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in cloth measuringand automatically computing apparatus and comprises various details ofconstruction and combinations and arrangements of parts which will behereinafter fully described and then specifically defined in theappended claims.

I illustrate my invention in the accompanying drawings, in which Figure1 is a top plan view of the device. Fig. 2'is a side elevation. Fig. 3is a longitudinal sectional view. Fig. -4 is a cross sectional view.Fig. 5 is a detail view of the actuating device, and Fig. 6 is a detailview of means for limiting the movement of the indicator.

invention,

Reference now being had to the details of the drawings by letter, Adesignates the casing of the computing and measuring de vice which maybe of any suitable material, such as pressed steel, and of any desiredshape, preferably of rect-angular form and resembling somewhat a pictureframe. The opposite sides of the frame have flanges A', the upperportions of which areI curved inwardly, as shown clearly in the detailsect-ional view of the drawings.

An index sheet, designated by letter B and made of any suitablematerial, isplaced within the opening in the frame and prefrablyprotected by glass and through which may be seen the p-rices peryard,calculations, etc. Journaled in suitable bearings in the opposite endsof the frame are two rock shafts C and C', each having rack teeth Dthereon, the former only of said shafts adapted to have a longitudinalmovement.

An angle lever E is pivotally mounted upon a pin E and is pivoted at E2to the shaft C. A depressible button F is mounted over one arm of theangle lever E and affords means whereby, when the button is depressed,the angle lever may be tilted and a longitudinal movement may beimparted to t-he shaft C. A coiled spring G is mounted upon and bearsagainst the shaft C and is provided for the purpose of returning thesame'to its normal position after having been given a forwardlongitudinal movement by the depression of the button F. The two shaftsC and C are adapted to rock in unison through the medium of the rod IIwhich is pivotally connected at its ends to the pins II, one fixed toeach shaft, a handle I-I2 being fitted to the shaft C for rocking thesame.

The indicating bar I has pawls I ivoted thereto which engage the ratchetteeth D, thus causing the bar4 I to move forward as a longitudinalmovement is imparted in one kdirect-ion to the shaft C. Said indicating'bar has adjustably mounted thereon a magnifying glass J which is adaptedto disclose certain calculations per yard after the material has beenmeasured and computed. 'The bar I is provided with a bushing K which hasa sliding movement upon the rod K fastened within the frame and servesas means to guide said bar.

Fixed to the shaft C is a series of pins, designated in the drawings byletters N, N', N2, N3 and N4, indicating in the arrangement shown Si,Ji, and yards, and for each of said pins is a depressible button O, adetail view of one of which is shown in Fig. 6 of the drawings, andwhich buttons O are adapted to be depressed in the path of one oranother of said pins in order to limit the longitudinal movement of thebar I in its calculating. Each button O is held at its highest or normalposition by means of a spring O2 fastened at one end of the casing andas shown in Fig. 6 of the drawings.

In order to return the bar I to its normal or start-ing position, acable Q is fastened to the bushing K and is adapted to wind about aroller L fixed to the shaft L and which shaft L is designed to be givena rotary movement through the medium of a coiled spring containedtherein and similarly constructed to shade rollers. A movable indicatingpointer R has a bushing R which is movable upon the shaft L and isadapted to engage a notch J inV the frame of the magnier, said pointer Rand the frame of the magnifier being set to disclose the price per yardthrough the magnifier before the material is measured.

The operation of my apparatus will be readily understood and is asfollowsz-The parts being arranged as shown in the drawings and theindicating bar I adjusted at its farthest limit to the left with thepointer R bearing opposite the price per yard to be calculated andengaging the slot or recess J, the cloth is moved over the apparatusand, in the event of it being desired to measure a half yard, the end ofthe cloth is brought opposite the button having the indication thereonand the latter depressed to throw the lower end thereof in the path ofthe pin N2, after which the operator depresses the button F which,through the medium of the angle lever, will cause a longitudinalmovement to be imparted to the shaft C a distance determined by therelative locations of the pins N2 and the button bearing the markingyard. As the pin N2 comes in contact with said button designating yard,the longitudinal movement of the shaft will be arrest-ed and thecalculation of the material at a particular price per yard will bedisclosed through the magnifying glass. As the shaft C is movedlongitudinally, the indicating bar I through the medium of the pawls Iengaging the ratchet teeth will be moved forward the proper distance.When it is desired to return the indicating bar to its normal position,the operator by turning the handle H2 may cause the two shafts havingratchet teeth thereon to rock in unison, thus releasing the pawls I andallowing the spring-actuated shaft L to reel up the cable Q upon thedrum or reel L and return the bar to its starting position. In the eventof it being desired to measure and compute at different prices differentnumbers of yards up to 42 for which the present apparatus is adapted, itmay be accomplished by the operator bringing the cloth or other materialopposite the one yard indication and depressing the button F for eachyard measured until 42 yards have been computed and which computationwill'be disclosed through the magnifying glass. In the eventof asuccession-of longitudinal movements being imparted to the shaft C, thelatter returning to its normal position each time a movement is impartedthrough the medium of the spring G, it will be understood that the shaftC', which is not adapted to have a longitudinal movement, will servetohold the indicating pointer and bar I from a reverse movement whilethe series of intermittentforward movements are imparted te the shaft C.

While I have shown and described a particular form of frame andmechanism for illustratingV my invention, it will be understood that Ido not confine myself to any particular form or shape of the frame orarrangement of parts or material, as` ob'- viously these may be variedat will without in any way departing from the spirit of the invention.
